NATHANIEL O. GOLDSMITH, OF NOR/WOOD, OHIO, ASSIGNOB TO THE WEIR- FROG COIVIPANY, OF NORWOOD, OHIO, A CORPORATION OF OHIO.

SWITCH-STAND.

Application filed July 6, 1915.

To all whomit may concern:

Be it known that I, NATHANIEL 0. GOLD- sMrn-I, a citizen of the United States, and a resident of the city of Norwood, in the county of Hamilton and State of Ohio,have

invented certain new and useful Improve-- ments in Switch-Stands, of which the following is a. full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to switch stands of the adjustable type wherein play is allowed for the connecting rod and its operative connection with the throw crank.

It has as its object the providingof certain structural improvements which simplify the manufacturing cost and protect the various connections in the stand from chance dislodgment and from becoming clogged by mud or ice, and has further as its object the providing of a 10st motion mechanism which is located between the switch rail head rod and the stand. These objects I accomplish by that certain con- I struction and arrangement of parts to be hereinafter more specifically pointed out and claimed and the various advantages noted.

In the drawings, Figure l is a rear elevation of the stand. Fig. 2 is an elevation of thevconnecting rod on a larger scale, partly broken away to show the structure of the adjustable nut and sleeve. Fig. 3 is a top plan view of the stand connected up to a switch. Fig. 4 is a sectional view through the cotter pin of one of the slotted adjustable nuts. F 5 is a vertical sectional view taken through the pin that connects the rod and the crank of the stand, said pin being shown in elevation. Fig. 6 is a longitudinal sectional view of a modified form of lost motion device for the connecting rod. Fig. 7 is an elevation of the same. Fig. 8 is a detail end elevation of the sleeve coupled to a switch stand crank in a modified manner. further modified form of lost motion device. Fig-10 is a detail elevation of a further modified form of sleeve and crank. Fig. 11 is longitudinal section of the part shown in Fig. 9.

Whereas but onetype of switch stand is shown and described, it will be understood Specification of Letters Patent.

that the various modified types of lost motion device are applicable to stands of different types. It is to be further noted that the various modifications, although differently constructed, all have alike the common characteristic of being protected from ice and sediment, and capable of being connected pivot-ally to the switch rail head rod. thus being capable of application with equal advantage to any form of switch.

I will first describe the principal form of lost motion device exemplifying my invention, together with the type of stand and the preferred method of coupling the stand to the connecting rod to which the said lost motion device is to be a plied. After the description of these parts, I will then describe the various modifications of lost motion device which have a wider a lication.

The connecting rod 1 of the device has a fork 2 for coupling it with the switch rail head rod 8 that throws the movable rails 4i, 5, of any desired switch. The stand has a base 6, in which is mounted the transverse shaft 7 that is preferabl integral with the switch lever 8. Journaled in the upper part of the stand is the vertical shaft 9 of the target 10. This target shaft extends out through the bottom of the stand and formed integral with it is the crank 11, which imparts motion to the connecting rod 1. For operating the vertical shaft, beveled pinions, 12 for the transverse shaft, and 13 for the vertical shaft are provided, said pinions be, ing forged integral with their shafts.

The connecting rod sleeve has a U-shaped base let to fit over the flattened end 15 of the crank 11. The body portion 16 of the sleeve extends in both directions from the U-shaped base, and slidingly engages over the screwthreaded end 17 of the connecting rod 1. The top central portion of the sleeve portion is cut away leaving an aperture directly over the U-shaped base portion, which said aperture is covered by an arched cover plate 18 that is adapted to be screwed down over the aperture. There 'is provided through the U-shaped base portion above and below an aperture for the securing pin 19, and the crank end 15 is also formed with a suitable i rod.

and not interfere with its sliding on the connecting rod.

In mounting the sleeve, the U-shaped portion is placed over the end of the crank. The pin is then dropped into place and the connecting rod slid into the sleeve. The rod will then be in a position to hold the pin in place and the cover plate 18 is screwed down over the aperture at the upper side of the sleeve to keep out the weather. A cotter pin may be inserted in the hole 21 in the protruding end of the pin.

The two adjustable nuts are of a special construction to provide for play in the movement of the connecting rod, to be securely held against backing elf, thus destroying all adjustments, and to keep mud and ice out of the space left for lost motion,

so that this will not be stopped 05. The

nuts accordingly have a screwthreaded body portion 22 which screws onto the end of the connecting rod, and a sleeve portion 23 which fits over the ends of the sleeve portion 16 above mentioned. The nuts are pro vided with inclosed slots 25, preferably four in number, to allow for quarter turns of the nuts, and the end of the connecting rod is slotted so that cotter pins 26 may be used to hold the nuts in any desired position. The nuts are to be positioned with relation to the sleeve so that the sleeve may slide the desired distance before striking the body portion of the nuts. The nuts are mounted, one on one side and one on the other side of the sleeve, and the sleeve portions of the nuts are to be made long enough to fully cover over the ends of the main sleeve in all positions.

Themodification shown in Figs. 6 and 7 comprises the rod 1 having the forked end 2 for connection with the switch rail head rod, and the screwthreaded end 17." The sleeve 30 in this instance, however. does not carry a depending U-shaped portion, but on the contrary extends horizontally over the end of the red, the outer end of the sleeve being expanded at 31 to form a hood to engage over the adjustable nut 32 on the end of the The sleeve then separates into two arms 33, 33, which can be coupled up to a switch stand crank, or if desired could be connected up with any desired member actuated by the said crank. The other adjust-able abutment nut is like the sleeved nut already described and has the screwthreaded body portion 22 and the sleeve 23 to engage over the inner end of the sleeve. It can be seen that this modification has the same advantages in supplying alost motion device of simplicity, economy and security, and is in addition capable of being used with any form of switch and switch stand by merely insetting it into the interconnecting mem bers between the switch and stand.

As shown in Figs. 8 and 10, a sleeve 4c0-is provided which may be of similar structure to the sleeve 16 formerly described, and it may be used with the two sleeved nuts 22 described in connection with said sleeve 16. However, the sleeves in this instance are mounted difl'erently on the switch stand crank end 15, the one in Fig. 8 having a U- shaped portion like the sleeve 16 but being connected to the crank oy an upwardly extending bolt l1, which merelyvscrews into the sleeve, and the sleeve therefor not being necessarily open atthe upper end for the insertion of the bolt. In the sleeve of Fig.

10, the means for securing it to the crank comprises two lugs 42, 12, which are pro vlded with apertures for the bolt 43, which couples the end of the crank. to the lugs.

The modification shown in Figs. 9 and 11 has a sliding sleeve 50, provided with lugs 51 for receiving a coupling bolt. The sleeve has both of its ends interiorl expanded at 52, to form hoods for slidably engaging over the nuts 53. These nuts are not shown as being slotted, but they may be slotted if desired. They have the enlarged ends 5% which form the abutmentsfor the ends of the sleeve.

It can be seen that the modifications now briefly noted enable my invention to beused with varying types of switches now in use,

or specially constructed for meeting the re quirements of peculiar situations.

It is believed that the various advantages resulting in the structure having been sutliciently mentioned during theprogress of the description, so as to require no further particular statement.
